1. Explain what the Google Ads auction is and how it works.

When an advert is eligible to show up in a search, it enters into the Google Ads auction. Through this auction, Google determines whether the ad can show for a particular search and in which position it’ll be displayed.

The Google Ad auction works like this:

  • First, the system locates the adverts for which the search keywords match
  • Google then filters out ineligible ads that do not match the requirements for ad quality or search intent
  • If the bid, quality of the ad, and the user’s search intent are good enough, this ad will be displayed

2. What is the relationship between an ad’s rank and CPC?

For CPC (Cost-per-click), the highest amount an advertiser will be charged is the equivalent of the smallest amount needed to maintain the position of their ad. It’s also important to recognize that higher CPCs are usually linked to ads that appear above the results of the search.

3. Explain what CTR means.

CTR is short for click-through rate, or the ratio between the number of people who see an ad and those who click on it.

4. How is CTR calculated?

To work out the click-through rate, divide the total number of clicks by the ad’s impressions.

5. How do you enhance the Google Quality Score of an ad?

There are a few factors that determine Google’s Quality Score of an ad, including the keyword and the ad text. For advertisers to maintain a high score, they should use fewer keywords and write targeted copy, which requires focusing on targeted ad groups.

6. What is the advantage of the Google API, and who should use it?

One of the main advantages of the Google API is that it provides advertisers with many tools, such as custom reports, automated account management, and the option to manage strategies for smart bidding. However, it’s recommended that only experts who have software engineering experience and have a solid understanding of the Google API  should use it.

7. What are the tools you use for keyword discovery?

Candidates may mention several keyword tools for research beyond Google, including SEMrush, SurferSEO, Ahrefs, and SpyFu. Even if they are not knowledgeable of the tool that your organization uses, they should understand the basics of keyword research and show that they are motivated to learn.

Google recommends that an advertiser should wait for between two and three weeks before they analyze the performance of a new Display Network campaign.
